A wrongful death lawsuit filed by the mother of a 13-year-old boy who went missing in 2012 and whose remains were found months later in southwestern Colorado has been dismissed due to a filing mistake.

KUSA-TV reports that Elaine Redwine filed the suit against her ex-husband, Mark, in June 2015 claiming that he was responsible for the death of their son, Dylan. Her attorney, Amber Cone, says the lawsuit was dismissed because it was filed four days after the statute of limitations expired.

Dylan disappeared from his father's Vallecito Lake house in November 2012, and his remains were found seven months later.

Cone says the suit was filed two years after the date the family was notified the remains belonged to Dylan, not the date his remains were discovered. The difference was about four days.
